Scientists have reached a step closer to realising car windscreens that will display the menu of cuisines being served at a user’s favourite restaurant on a particular day.
US researchers from Purdue University say that they have created a proof-of-concept screen from nanowires, which represents a model for future technologies that may create hi-tech digital newspapers like in the movie Minority Report, or display the menu of a restaurant as the user walks down the street.
“It could be used to project GPS navigation information on a car windshield. It would be like driving in a video game,” said David Janes, a scientist at Purdue University.
The researchers embedded organic light-emitting diodes (OLEDs) in transparent nanowires to create the new display.
They say that such displays could be placed directly on a car windshield or on eyeglasses to overlay information on real objects. Coupled with a computer, the same material may allow a user to look at a restaurant while walking down the street, and view its menu, without stopping in.
Given the transparency and flexibility of the display, it may also be used to create e-paper or e-books capable of being continually updated with videos and images.
The scientists, whose research paper appears in Nano Letters, hope to develop a large-scale prototype within five years.
